Forms

nadar (first-person singular present nado, first-person singular preterite nadei, past participle nadado)[1]

Etymology

It is inherited from Latin natō (“to swim, float”), already Old Galician-Portuguese nadar in the oldest texts.[2][3][1][4] The Latin verb is a frequentative formed from nō (“to swim”).[5][1]

The same Latin verb is Galician nadar, Spanish nadar, Catalan nadar and Occitan nadar; a variant *notāre lies behind Italian nuotare and Old French noer.[6][1]

De Vaan traces the Latin verbs to Proto-Indo-European *(s)neh₂- (“to swim, float”), with its participle *(s)nh₂-to-, the source of the stem of the frequentative;[7] Old Irish has a cognate verb for “to swim”.[7]

Earliest recorded meaning

The Cantigas de Santa Maria already use the verb: in cantiga 33 a man would be saved per nadar “by swimming”, and cantiga 225 has dentro no sangui nadando “swimming in the blood”.[8] Houaiss dates the verb to the 13th century from Cunha's medieval index.[2][3]

Semantic evolution

The figurative “to be soaked in, steeped in a liquid” is old: the Miragres de Santiago say that the horses swam in the blood of the Moors who died there.[8] Morais's dictionary of 1789 adds nadar em delícias “to revel in pleasures” and eyes swimming in wine or sleep.[9] Houaiss and Aurélio record the senses “to have in abundance” (nadar em dinheiro) and, of clothes, “to be far too large for someone”.[2][10]

In Brazil, informal nadar also means “to be lost, not to understand”.[2][11] Common phrases are nadar como um prego “to swim like a nail”, that is not to swim at all, and nadar contra a maré “to swim against the tide”.[12][13]
